Application-filed February 27, 1930. Serial No. 431,710.

Qur invention relates to an improved decapping tool, and has as its objective to .provide a tool for the removal of both screw-caps and friction-caps from bottles, jars and other,

g containers.

It consists of a frame having an aperture of converging straightedges, along one of which edges we dispose a fixed gripping strip orv element having a biting," preferably sawtoothed, edge, having raking teeth the other edge of said aperture carrying a sliding element, having humps arranged to center a screw-cap between them, the sliding element being arranged to carry the screw-cap 1nto I -biting engagement with 'the gripping element, said biting engagement serving to hold the cap against rotation, whereupon the container is twisted to unscrew it from the cap.

For use in removing a friction cap, we form a hook on one of the outer ed es of said frame which enables the tool to e used as a hand-lever for the removal of such caps.

I Drawings In the drawings- Fig. 1 is a plan view of a tool embodying our invention, mounted in a wall-bracket.

Fig. 2 is a front elevation of the same. Fig. 3 is a plan view of' said tool, belng so used as a hand-lever in remov ng a friction-' cap.

Description The frame A is apertured to produce the converging opposed inner straight edges 2 and 3 and the hook 4 is formed on one of the outer ed es of said frame A. Upon the face of the i rame A the gripping element 5 is fixedly mounted; I have shown 1t as being mounted removably by means of screws 6.

The inner edge of the gripping element 5 is from its container.

shown, with twin humps 13-13, the projecting edge of each of said humps 131-3 con sisting of saw-teeth 14, which teeth 14 are raked in the opposite direction to that of the raking of the teeth 7 on the gripping element 5. The cleats 9 extend in o posite directions from the upper and lower faces of the frame A, so that the frame A may be reversed in the wall-bracket 8 to perform the opposite functions of screwing and unscrewing the screw cap B. In Fig. 1 we have illustrated said screw-cap B in proper engagement with the tool for the purpose of unscrewing and removing said cap B. When it is desired to use the tool for the purpose of seating the cap 05 ,B, the frame A is reversed in the wall-bracket v 8, the screw-cap B is again seated within the tool and rotated in the direction indicated by the arrow in Fig. 2 to screw the cap securely in place. A

When it is desired to remove afriction-cap from a container, the tool 1s removed from its seat in the wall-bracket 8 and used as a hand- I tool, the hump 4 engaging the friction-cap C,

to pry said cap C from its seat, the apphca- 7 tion being-as shown in Fig. 3.

As is well known in the practical use of screw-caps, such screw-caps are frequently seated so firmly upon the containers when delivered to the consumer, as to make the re 0 moval of the screw-cap a matter of great difficult Bymeans of our invention it'ismade possi le to secure a bite upon the screw-cap which will enable it to be readily unscrewed Various modifications of the illustrated form of our invention maybe effected without departure from our actual invention as defined in the appended claims.

We claimv 00 1. A decapping tool comprising a frame,

attaching means on the frame for reversible engagement with a fixed support, said frame being apertured to provide converging opposed inner straight edges, a fixed toothed a5v gripping element on one straight edge, and a slidable gripping element on the other .straighted e, said slidable elementhaving a pair of toot ed humps.

2. A decapping tool comprising a frame,,100

attaching means on the frame for reversible engagement with a fixed support, said frame being apertured to provide converging opposed inner straight edges, toothed gripping elements carried by the straight edges, the teeth of one element raked in a direction opposite from the teeth of the other gripping element, one gripping element being slidable to grip an object between the two gripping elements, and the frame bein reversible to on ago an object therein against movement eit er in a clockwise or anti-clockwise direction.
